B. ELEMENT SIZE VERIFICATION
All elements are marked with both wattage and voltage. Verification can be made by measuring the ohms
resistance across the terminals of the elements. Element must be disconnected from the circuit. The following
table gives resistance in ohms for all elements used in commercial electric water heaters.
Element ohms resistance should be within ±5% of the above values.
Examples: Elements with an ohm resistance of 14 ohms indicates that it is either a 3,000 watt/208 volt element
and/or a 4,000 watt/240 volt element (dual rated type).
CAUTION
NEVER OPERATE THE HEATER WITHOUT FILLING WITH WATER PER THE FILLING INSTRUCTIONS. FAILURE
TO DO SO WILL DAMAGE INTERNAL PARTS.
